BURTON D. KNICKERBOCKER, OF CHICAGO, ILLINOIS.

BATH-BRUSH WITH DETACHABLE HANDLE.

Specification of Letters Patent.

Patented Tune 12, 1906.

Application fusa December 31.1903. serial No. 187,375.

To all whom it may concer-7c:

Be it known that I, BURTON D. KNICKER- BOCKER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement inBath-Brushes with Detachable Handles, of which the iollowing is a full,clear, concise, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

My invention relates to an improved bathbrush with a detachable handle.

T In Letters Patent N o. 666,759, issued January 29, 1901, I havedescribed a bath-brush made of rubber and containing an interior chamberadapted to be connected with a suitable source of water-supply andcarrying upon its face a series of teeth, said teeth havingV ductsformed therein extending from said interior chamber through the teeth,said teeth constituting the scrubbing-surface of the brush. p Thepresent invention relates to a brush of thisgeneral type provided with adetachable hand e. It will be understood, however, that my improvedhandle may be used with other forms of brush than that above described.

The object of my invention is to provide a handle which will securelyhold the brush when being used therewith and which can be readilydetached thereform when it is desired to use the brush with the handleremoved.

Referring to the drawings, in which the same reference charactersindicate similar parts throughout the several figures, Figure 1 is aplan view of my improved brush-holder with the brush in position. Fig. 2is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is an end View ofthe holder and brush. Fig. 4 is a sectional view showing the manner ofattaching the brush and the handle. Fig. 5 is the same as Fig. 4 withthe handle removed.

Fig. 6 is a lan view of a portion of the handle,

showing t e supply-tube in dotted lines and Fig. 7 is a perspective viewof the connection for attaching the supply-tube to the brush.

Referring now to the drawings by reference characters, my improvedhandle 1 consists of a back 3 and a handle proper, 4, attached theretoin any suitable manner, preferably by screws 5. The back3 is preferablymade of flexible material, and to impart additional flexibility theretoa portion thereof may be cut away, as

shown in Fig. 1; but this is not essential, the back beingmade rigid, ifdesired. The back 3 carries studs 6, which are secured theretopreferably by nuts 7, said studs being formed withlenlarged ends 9. Anysuitable projection may be provided upon the back 3 in lieu ofsaidstuds.

The brush 10 has a duct 11, communicating with an interior chamber 12,adapted to be connected by a tube 13 and faucet connection 14 with asuitable source of watersupply and carries a series of teeth 15, havingducts 16, formed therein for conveying the contents of the chamber 12 tothe scrubbing-surface of the brush. Formed, referably, upon the ends ofthe brush are ugs or ears 17, having apertures 18 formed thereon, saidapertures being formed with irregular bores 19, adapted to hold the lugsor ears 17 infirm engagement with the studs 6, carried by the back 3 ofthe holder 1. While I prefer to form lugs or ears upon the brush, asabove described, such construction is not essential, and any suitableform of projection thereon or any suitable form of aperture therein maybe adapted in lieu of the lugs or ears described. To give a greaterdegree of resiliency to the brush, I prefer to mount same so as to leavea space between the brush and the back piece 3 of the handle, as shovmin Figs. 2 and 4.

One end of the tube 13 is attached to a coupling 20, which extendsthrough the duct 11, formed in the brush, and communicates with theinterior chamber 12. It has been found desirable in practice to providemeans for distributing the water admitted through the duct 11 in equalquantities over the entire interior of the chamber 12 in order toproduce a uniform iiow through the ducts 16 in the teeth 15 of thebrush. Otherwise the water has been found to collect in the end of thebrush farthest from the duct 11 and to flow in larger quantities throughthe ducts 16 located at that end of the brush than through the ducts atthe other end of the brush. I prefer to accomplish this result byproviding a projection 21 upon the coupling 20, said projection having aseries of holes 22 formed therein, as shown in Fig. 7. It will beunderstood, however, that the form of the projection 21 is notessential, as the end of the coupling might be formed in many differentways and carry differently-formed openings to accomplish the sameresult.

The handle proper, 4, is preferably curved IOO IIO

to permit the tube 13 to pass through the same, and I prefer to curvethe edges 23 of the handle 4 to normally inclose the tube 13 and permitthe tube to be inserted in and removed from the handle between thecurved edges thereof, as shown in Fig. 6. I do not wish to limit myselfto the particular construction of the handle described, as other formsof handle might be'used with or without the tube passing therethrough,and other means might be adapted for retaining the tube in and removingthe same from the handle.

While I have described my invention with particular reference to thedetails of' construction, I do not wish to be understood as limitingmyself to such details.

I am aware that many changes might be made in the details ofconstruction without departing from the spirit of my invention, and Itherefore claim the right to make such modifications as fairly fallwithin the scope of my invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

l. In combination, a brush having a flexible back and teeth formed uponsaid back, said back being hollow and provided with interstices, a tubeconnected to said back, a frame attached to said flexible back andsupporting the same, and a handle mounted upon said frame.

2. In combination, a brush having a iiexible back and teeth formed uponsaid back, said back being hollow and provided with interstices, a tubeconnected to said back, a frame attached to said flexible back andsupporting the same, and a tubular handle mounted upon said frame, saidtube being arranged within said handle.

3. In combination, a brush having a flexible back and teeth formed uponsaid back, said back being hollow and provided with interstices, a tubeconnected to said back, a

frame attached to said flexible back and supporting the same, and atubular handle mounted upon said frame, and provided with a longitudinalslit, said tube being arranged within said handle and adapted to passthrough said slit toplace the same within the handle and remove the sametherefrom.

4. In combination, a brush having a flexible back and teeth formed uponsaid back, said back being hollow and provided with interstices, a tubeconnected to said back, a

frame supporting said brush, means attaching said frame to said flexibleback and capable of permitting said brush to be readily detached fromsaid frame, and a tubular handle mounted upon said frame.

5. In combination, a brush having a flexible back and teeth formed uponsaid back, said back being hollow and provided with interstices, a tubeconnected to said back, a frame supporting said brush and provided withstuds, said studs being placed in holes formed in said back to connectsaid brush to said frame, and a handle mounted upon said frame.

6. In combination, a brush having a iieXible back and teeth formed uponsaid back, said back being hollow and provided with interstices, a tubeconnected to said back, a frame supporting said brush, mea-ns attachingsaid frame to said flexible back and capable of permitting said brush tobe readily detached from said frame, and a tubular handle mounted uponsaid frame, said tube being arranged within said handle.

In witness whereof I have hereunto subscribed my name in the presence oftwo witnesses.
